1 Claim. (oi. till- 6) A further object of the invention is to provide a particular combination of spoke and disk structure constituting the body of the wheel, a

=16 portion or such structure fulfilling the double iunction of a brake drum and wheel body part.

Other objects of the invention including details oi the means for securing the parts of the wheel structure together and other details of 20 structure will become apparent from the following detailed description of a preferred embodiment oi the invention, which embodiment is fully disclosed in the accompanying drawing in which:

25 Figure l is a partial vertical sectional View through the wheel structure of my invention taken on line l--l 01 Figure 2;

Figure 2 is a fragmentary side elevation of the wheel; and 30 Figure 3 is a fragmentary vertical sectional view disclosing a modified form. 01' securing means for the wheel body sections.

In one embodiment selected for illustration, there is disclosed in Figures 1 and 2 a conven- 35 tional hub structure It and rim structure I? adapted to be secured together by my novel wheel structure. This structure comprises a brake drum member I, the angle included between the braking flange l6 and head l8 of the drum being less than a right angle, the head preferably being integrally secured as by welding to a flange portion 20 on the hub structure.

A disk body member 22, constituting an im- 45 poi-tent feature of my invention, is preferably i'ormed from suitable stock material, spoke portions 23 being formed in its outer periphery. Each spoke member is preferably shaped to provide a channeled section, and at its base merges 50 with an imperforate section 26, the material of which is preferably pressed out to nest with and be supported upon the juncture of the head and brake flange structure of the drum. The outer ends or the spokes 26 are adapted to be secured on to the rim i2, and the inner peripheral edge or the disk body is adapted to be integrally secured to the hub it,

The disk body 22 is then severed at 28, Figure l, to provide inner and outer wheel body sections. The inner dish body section'is then preierably welded at 27? to a flange 38 on the hub and at its outer periphery is'preferably welded at, 32 to the head of the brake drum. This structure provides a very rigid triangular sectioned inner wheel body member adapted to support the somewhat yieldeble outer wheel spoke section previously described. The impericrate inner portion 26 of the outer wheel member is preferably provided with a pluralityof spaced lugs 3% to receive nuts 38 threaded upon studs 38, the latter being preferably integrally secured to the inner junction oi the oheadend flange oi the brake drum and extended through openings in the head and outer periphery of the inner disk body portion.

A verysimple method oi fabricating the wheel body is thus provided, the outer wheel body portion being rigidly supported by the brake drum and eiiectively mating with the inner wheel body portion by virtue oi the aforementioned severing step in the method or manufacture.

The outwardly extending spoke portions 24 are preferably integrally secured to the rim as by welding and are so inclined as to readily take I both normal and side thrust loads in compression as prolongatlons or the inner wheel body members 22 and i8. i

If desired, the lugs 34 of Figures 1 and 2 may be supplanted by an annular ring member S0 of Figure 3, which member is preferably integrally 35 secured at 42 at its outer periphery to the impertorate portion of the outer spcked wheel body member While there has been illustrated and described two embodiments o! my invention, it is not my 40 intention to limit the scope of the invention to these particular embodiments or otherwise than by the terms or the appended claim.

I claim:

A wheel structure comprising a triangular sec- 4 tioned body member, including a hub, a brake drum having a drum head secured at one end oi said hub, and a hub disc secured to the other end oi said hub and having its periphery secured to said brake drum head adjacent the periphery thereof, a demountable rim-supporting structure comprising a rim, and a rim-supporting annular disc, said disc being cupped adjacent its inner periphery to embrace said brake drum and v extend inwardly over the older portion or the drum head, the inner periphery ct-the annularhold circle, an annular flange secured to one of disc being or substantially the same diameter as sa d d s ove app sa u der and inner the outer diameter of the hub disc, and adapted p p a d a s r s 0! bolts ar an d n t e to seat on an annular shoulder formed by the bolt circle pe z t ou h s d a nular flan e periphery or the hub disc, said shoulder and enand brake drum head.
